Backup NSS filesystem with Proxmox Backup Server ?

[theansweris42]

Hello everyone,

We are very active in the former Novell, now MicroFocus OpenText, sector.
As a result, we have many customers, some with very extensive eDirectories, as well as Open Enterprise Servers based on Suse Linux SLES 15.
We have now migrated many of these customers from VMware single systems and VMware clusters to corresponding Proxmox systems and clusters.
Now, of course, we also want to migrate/simplify the backup solution from various platforms to PBS.
We are currently running a PBS in a pilot project as a VM in a Proxmox 3-node cluster with datastores on NFS, SMB, and iSCSI.
Backups via PBS are problem-free and work cleanly and error-free.
However, we have found that the pools and volumes of an OES (Open Enterprise Server) cannot be backed up as file system backups with PBS, which consequently rules out the use of PBS under OES with an NSS file system.
The question is, is there anyone here who is using this productively, or is backing up NSS file systems on PBS's roadmap?

Perhaps we've simply overlooked something and would be truly grateful for any crucial information.

Thank you for your answers and suggestions!

Regards
Thomas

No one here who could answer my question?
I received an email reply from a user named "news", but I don't see his reply here.
The user "news" asked why we want to use an NSS file system. We should simply use ZFS and that would be fine.

For the user "news"

My question isn't about running PBS on an NSS file system. Rather, we want to back up a Suse Linux Enterprise (SLES15 SP6 with OES extension from MicroFocus) VM running as a VM in a Proxmox cluster with shared Storage on ZFS Filesystem.
From this backup, we not only want to restore the entire VM (this works great with PBS), but we also want to be able to perform a single file restore from the backup.
The VM has an NSS file system (not ext4, not xfs, not any other Linux Filesystem...).
But that doesn't work because the VM's NSS file system isn't recognized by PBS.

If any of the developers are reading this:
Can PBS back up an NSS file system, or is this planned or on a roadmap?
If not, is there a feature list where such a thing can be suggested?

Thanks for your feedback.

Thomas
